Analytical results are then validated by simulations.","PeriodicalId":322589,"journal":{"name":"2010 Fifth International Conference on Digital Telecommunications","volume":"22 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120862055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have tried to give solutions to several issues that have arisen like building a large and accurate database within a reasonable time. A short description of the database is given and some statistics are collected in order to show its evolution in several stages of the project. Embedded training technique has been used for training triphones. As a consequence, the alignment problem has been studied and a solution is proposed for it. The final purpose of these attempts is to obtain substantial results in speech recognition for Romanian language that can be used as baseline for further results.","PeriodicalId":322589,"journal":{"name":"2010 Fifth International Conference on Digital Telecommunications","volume":"01 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124424112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The number of cameras is so high now that the operators surveying each video stream are not sufficient. Many companies currently propose systems that analyze the video stream for sending automatically event messages for intrusion, abnormal comportment or situation. We develop a framework with web services, enterprise Java Beans [6] and a complex event processor bean to manage all video event messages. This new framework allows the integration of new generation of video surveillance systems with more flexibility, scalability, interoperability and productivity.","PeriodicalId":322589,"journal":{"name":"2010 Fifth International Conference on Digital Telecommunications","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132436239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A multiwavelet transform is first applied to a pair of stereo images to decorrelate the images into a number of approximation (baseband) and detail subbands. Information in the basebands is less sensitive to shift variability of the multiwavelet transform. Basebands of each input image carry different spectral content of the image. Therefore, using the basebands to generate the disparity map is likely to produce more accurate results. A global error energy minimization technique is employed to generate a disparity map for each baseband of the stereo pairs. Information in the resulting disparity maps is then combined using a Fuzzy algorithm to construct a dense disparity map. A filtering process is finally applied to smooth the disparity map and reduce its erroneous matches. Middlebury stereo test images are used to generate experimental results. Results show that the proposed technique produces smoother disparity maps with less mismatch errors compared to applying the same global error energy minimization technique to wavelet transformed image data.","PeriodicalId":322589,"journal":{"name":"2010 Fifth International Conference on Digital Telecommunications","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133876464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Free-riders exploit such aspects of the protocol to maximize their downloads and minimize uploads, resulting in crippling the system and benefiting only themselves.

This paper studies the implementation and testing of a new power-aware algorithm, PSWA, associated with a Cache System, and tested with the WRP routing protocol, in a Mobile Ad hoc Network scenario. A scheme that does not use the sleep schedule for the nodes it was used, nodes automatically fall asleep if they do not deal with data and routes. In the simulation scenario the WRP was chosen because it has a better performance in real-time traffic, and this type of traffic is commonly used today. The simulation results show an important decrease in energy consumption close to 10% with the association of the new power-aware algorithm.","PeriodicalId":322589,"journal":{"name":"2010 Fifth International Conference on Digital Telecommunications","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131663497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Federation of Personal Networks (Fednet) is a group-oriented network of PNs. Since behind each PN there is a person, i.e., the PN owner, the cooperation of the PNs reflects the social behavior of the PN owners and therefore a Fednet can be seen as a social network of PNs. In this paper, we look at the Fednets from the ‘social’ angle and discuss how the Fednets can benefit from using reputation. We propose a reputation-based framework for Fednets and present ideas on applying reputation information for service management and reward mechanisms in Fednets to improve the quality of cooperation between the PNs.","PeriodicalId":322589,"journal":{"name":"2010 Fifth International Conference on Digital Telecommunications","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131533144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consumers are growing to expect ubiquitous, constant connectivity and access to all manner of information applications. Service providers, large and small, must simultaneously find ways to offset the declines in traditional sources of revenues while drive top-line growth. Fixed Mobile Convergence (FMC) solutions are promising to offers advantages for both consumers and service providers and is gaining momentum in the marketplace as operators are realizing the market opportunities for creating new revenue-generating services. FMC solutions are promising to deliver the long awaited hand off of calls/calling features between wire-line and wireless networks. This article first defines the concept of FMC and it then several prominent concepts in the fixed mobile-convergence are analyzed.
